DOOR-HANGER.

Be it known that I, G oRGE M. P1PER,a citizen .-of the United- States,.residin at Cedar Falls, in the county of Black awk and State of Iowa, have invented certain new .andfuseful Improvements in. Door- Hangers, of whichthe following is a specification, reference being had to the accom-' palhling drawings. I

, y invention relates to improvements in door-hangers, and specifically the object of my. invention is to provide a hanger /between hinged doors and a-carriage movable upon a trackpositioned thereover, which may always be operable any posi tions of the doors relative to'thetrack without coming to a dead center.

It is also an' object of the invention to provide a door hanger which may be used on a track laying parallel throughout its entire length to the supporting door frame and which hanger co-acts with the inner door of a pair of pivotally connected doors, al-;

' track.

lowing said inner doors to fold back substantially parallel to each other and to the These objects I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in. which Figure l hanger as operatively connected between acarriage on a track and a vdoor thereunder parts of the track and door being broken away; Fig.2 is a plan of the hinge-part of said hanger; Fig. ;3 is a cross-section of said track, showing said carriage therein, and

Fig. 4 is a horizontal section taken through the doorway of a building, showing doors hinged to a jamb thereof and to each other and operatively connected to an overhead track by my improved hanger, dotted lines indicating difl 'erent opened" positions of said doors;

Similar numerals of reference denote corresponding parts throughout: the several vlews.

Referring first to Figs. 1 to- 3, the numeral 19 denotes a tubular track supported on a building 12 above its door-opening and doors 8-9. The bottom of the track has-a longitudinal slot 20, providing a pair ofv parallel runways upon Which may roll .a

carriage havin rollers 18 pivotally mounted on a body 1 said body having a hanger 16 with depending threaded stem 13.

The'inner door 9 is hinged at" 11, to one has its part 1 secured to an upper corner of the outer door by means of bolts 7 The parts 1 and 2 have a prop or rule-joint 4, which thus limits the relative movements of these parts so that they cannot swing to or beyond-a dead-center with said doors; The

part-2 has a vertical orifice near its free end to permit it to be mounted to rock on the stem 13, and is secured thereon forvertical adjustmentby means of nuts 14 and 15 en gaging its' under and upper surfaces.

The track 19, is, in Fig. 4, shown as supported on the bui1ding'12 set ofi from the doors 8-9 when the latter are-closed, for

the purpose of adiagrammatic illustration,

the usual position of said track being immediately above and in the plane of the doors when the doors are'so hinged to the building as to underlie the track.

When the doors underlie the track, the hinge ,parts 1-2 are fully extended as shown in Fig. 2'.- In Fig. ,4, the dotted linesdisplay one position of said doors 89 when folded together so as to extend outwardly at a right angle to: the building, in which position the parts are' flexed' at less than a right-angle. The second dotted line position shown, indicates the position of said'folded doors when swung toward the building.

Ifthe track were immediately above said doors, the parts l2 would be in the full line positions shown in Fig. 2, with the doors positioned closely parallel to the building, but the parts prevented'by its pro joint from passing to or beyond a dea -center. However, it will be obvious that when. thetrack is spaced away from said doors as shown, the parts will not arrive at their stopped positions, r

This arrangement o'f the doors, their relations to each. other, to the building and said track as connected to. the latter .by said prop-joint I hinged movable door-hanger,

I is

" i fin mounting the parts on a building the said parts are easily adjusted so as to always ter.

permits the doors to be freely swungto any position outwardly, .and be as freely ,re-

turned to a .closed position, without any binding, or interference with their operation due to the hanger parts passing relatively to or; beyond a position-of dead cen- The doors are thus'su ported from freely movable, an easily actuatedj 'bm a closed to an entirely opened position, and the reverse. a It should als'obe noted, that the use of 2 my improved door-hanger and hinge or link permits the doors to be positioned either in a vertical plane assing through said track,- o'rbeyond said p ane as illustrated, whereby operate .as' described, whereby much inconvenience is avoided.

Having described my invention, what I claim as new, and'desire to secure by Letters 7 Patent, is:

.the outermost doorto a carria head track, 1 whereby the 1 oors can be 1. The arrangement of hinged to each other and to a jamb-of a doorway, with a. swiveled, rule-jointhinge-connection of swung to any open-position without shifting the parts of saidhinge-connection to or beyond a" dead] center, and whereby the "doors may belocated in orbeyond the plane 1 of the track. v

In a-' door structure, the combination of a straighttraok rigidly'mounted parallel to thedoor opening, a plurality'of hingedly connected doors the outerone of which is hinged .at one side of said door opening, a hanger mounted totravel on said track, and I means. connecting said hanger with the in-. I

ner door allowing it to mdvedaterally of above the; door and below the hanger. on an'over the track in a manner permitting said doors 'to fold back substantially parallel to each other and to said track.

hanger mounted to travel on said track, and I a horizontally swinging member extending between said door hanger and the inner door and: pivotally connected to both in manner permitting said -doors to fold back substan-' t y track.
